-**Features:**
-
-- Robust and efficient API routes for running a chat platform.
-- Distributed notification system, allowing any node to be seamlessly connected.
-- Simple deployment, based mostly on pure Rust code and libraries.
-- Hooks up to a MongoDB deployment, provide URI and no extra work needed.
-
-## Stack
-
-- [Rocket](https://rocket.rs/) (REST)
-- [Async Tungstenite](https://github.com/sdroege/async-tungstenite) (WebSockets)
-- [MongoDB](https://mongodb.com/)
+Note: `january`, `autumn`, and `vortex` are yet to be moved into this monorepo.
